A must for women A plus for men

Longan, translated literally as "Dragon Eye", is a fleshy fruit extremely popular in Asia as a snack and as an ingredient in tonic teas and formulations. It has a slightly chewy texture with a unique sweet smoky flavor. There is a saying in Chinese herbalism that "women are governed by blood." As a result, women generally benefit significantly from blood tonics. Longan is a great blood tonic, often combined with other blood tonics such as Dang Gui and peony root to make blood-building teas and formulations. It is a great Qi tonic for building up your everyday energy. Consumed regularly, Longan boosts temporary energy as well as long term vitality, yet it is not a stimulant like caffeine. It gives you energy while simultaneously relaxing you. Longan promotes tranquility. Longan has been found to promote deep, refreshing sleep. It can be used to enhance memory and steady the nerves by fortifying blood and Qi. Longan is a famous beauty herb. Longan adds luster and beauty to the skin.
